Problems with Dual monitor

Hey guys This is my First time to use another monitor with Flight simulator Here is what I Have nvidia 6600 GT 128mb Dual DVI plugged into IBM CRT 21" Primary monitor and 17" EIZO CRT as a secondary monitor .. Utilizing such setup for doing any Task with windows and everything goes fine .. I mean I can use the secondary monitor to watch a movie and use the other monitor to browse the net and do other tasks .. but when I try to use it to expand my view in FSX the screen just flickers with dots all over the screen !! I do everything as illustrated by FSX .. I dragged the new window to the secondary monitor but FLICKER Flicker Flicker in the secondary monitor .. Tried to reduce the Detail level to the least minimum but still the same Flicker plus the pull down menu get hazzy and I loose the characters ! even If i close the new view still the secondary monitor has this flickering picture although I closed it before .. !! any help with this ? is my graphic card low for such thing ? or do I have to install a particular software like wideview ?! or what should I do ?! I tried taking a screen shot but the picture was clear !! Please help me with this coz I really want to expand my experiences with FSX I have the latest drivers installed for the graphic card installed tried all different resolutions was not successful at getting the new window to work in a good way in the secondary monitor ! Help me :)Regards haithamEdit system specs : WinXPproSP2 - FSX with acceleration installed - AMD 3500+ 2.2GH z Nforce3 ultra Mobo 2 GB DDR Maxtor HDDs -
